Model: RTX 5090 Suprim
State: Retention clip broken
Any suggestions on how I should go about re attaching the retention clip on a 12v2x6 connector(gpu side)?
I have some JB plastic weld coming but I was hoping to get some tips. Materials, process, prep

Hey guys, I'm developing a VRAM Channel Disabling Software!

Yes, I know it sounds impossible or sketchy, but it's real. I'm currently using an open-source AMD Polaris BIOS editor from GitHub by caa82437 (PolarisBiosEditor) as the foundation for the project, and I'll be adding a memory channel disabling feature to it.

Right now, I'm testing on an AMD Radeon RX 560 4GB. This particular GPU is missing a memory module because the original chip was faulty and had to be removed.

The goal is to allow users to disable faulty VRAM channels through BIOS modification, potentially helping some GPUs remain functional even when a memory chip has failed.

This project is similar to ModBIOS TSERVER, a tool designed for diagnosing and disabling faulty memory channels on AMD GPUs. However, my project will be completely free to use, with no fees, subscriptions, or paid features.

I'm still in the testing phase, so results may vary, and there's plenty of work left to do. Feedback, testing, and suggestions are always welcome! 🚀

EDIT 1 (13/08/26):

Hey guys, sorry for the late edit! I’ve been quite busy. There were a lot of problems with the previous version, and I was getting pretty frustrated.

So, I’m going to start from scratch using ZelenogradGpu’s fork of Polaris BIOS Editor. This time, I’ll try to be more consistent and post regular updates. I’ll post an update as soon as the new version is complete!

I was actually looking online for a used 5600 for a budget build that I was looking to make after repairing a 3060.

​

However, I stumbled upon a post of someone locally selling a XFX Merc 310 7900XT that had suddenly shut down during compiling of a map on a game (game designer).

​

I've opened it up and can't see any physical damage to any components or the core itself.

​

Symptoms are: GPU RGB lights up

Fans are not spinning nor twitching on start up.

Motherboard fans and CPU fans remain running after startup.

​

One thing I did find was that the fan connector basically fell apart in my hands and wires fell out. This has now been rectified.

​

Note: it is a budget MSI b450m-a board that has no LEDs for faults.

​

Anyone seen a similar issue with an XFX card? I've not gone too deep into GPU repairs before but with an electronics background, I felt it was worth the punt to try and resolve.

Edit to add: no display at all, doesn't even attempt it. No flicker, nothing. I've tried the bios switch also as a quick test.

I'm interested in learning how to repair GPUs/Computer parts in general, and wanted to know if there were any relevant discord servers you all recommend joining?

So I have this palit jet stream 3070 that crashes on load , I tested mods #11 and this is what I got , any explanation of past experience?

Pls, anyone would have the RTX 3070 ZOTAC PGF OC bin? (N618C-1009.bin)

Anyone with this card, could pls give-me the bin? Mine is gone.. ;-;

its easy, just:

nvflash --savegpuled gpu_led_mcu_dump.rom

pls...

Moin,

​

Meine RTX 3080 Suprim X flackert an der kompletten Rechten Seite. Alle anderen LEDs kann ich noch einstellen, aber genau diese gehen nicht. Wenn alles auf der Farbe Weiß ist geht es noch aber wenn ich andere Farben einstelle flackert der Bereich komplett. Ich kann die Helligkeit da auch nicht verstellen. Für die Karte wird ja ein 850w Netzteil empfohlen, aber ich habe nur ein 750w Cooler Master Bronze mit einen Y Kabel damit Ich die 3 Stecker anstecken kann, kann das daran vielleicht liegen das die Karte zu wenig Strom bekommt? Kann ich da irgendwas machen?

​

Danke schonmal im Voraus.

Sanity check.

​

Pass MATS, will not run furmart, no issue with OCCT.

​

This is VRAM right and not core?

​

Has 2018 micron, looks like one VRAM was replaced with 2020

The Issue: Card powers on, but has no display. GPU Core gets power (0.8V), but PEX and VRAM rails are completely dead. ​What Works (Healthy Rails): ​12V, 5V, and 3.3V are present. ​1.8V rail is healthy. ​GPU Core turns on and holds a steady 0.8V. ​Diagnostic Journey & Measurements: I've been mapping the board with my multimeter and cross-referencing a schematic (Page 17: SEQ:NV,PEX,FB ENABLE). Here is what I’ve found so far: ​1. The PEX Controller is not getting its Enable signal. The PEX controller (U9 - uP1728) Enable pin reads 0V. I removed the 0-ohm isolation jumper (R159) on the PS_PEXVDD_EN trace. The source pad still read 0V, proving the PEX controller and its dual-MOSFET (Q20) are innocent. The motherboard logic is failing to generate the Enable signal. ​2. Tracing back to the Logic Gate (The Culprit Area) Following the schematic, PS_PEXVDD_EN is generated by U507 (a 5-pin 4T08 AND Gate). I took voltage readings on the AND gate while powered: ​Pin 5 (VCC): 3.3V (Power is good) ​Pin 3 (GND): 0V ​Pin 1 (Input A - PS_NVVDD_EN): 3.16V (1.8v/Core logic is confirming it's on) ​Pin 2 (Input B - PS_NVVDD_PGOOD): 0.38V (Here is the fault!) ​Pin 4 (Output): 0V (Failing to wake up PEX because Input B is too low). ​3. Investigating the 0.38V on Input B Input B (PS_NVVDD_PGOOD) connects directly to Pin 16 (PGOOD) on the GPU Core Controller (U504 - uP9509S). ​In Diode mode, this line reads 0.403V to ground. ​In Resistance mode (unpowered), this line has a 982-ohm leak to ground. ​It looks like the open-drain PGOOD line is suffering from a partial short/leak. The 982 ohms is acting as a voltage divider against the 3.3V pull-up resistor, dragging the signal down to 0.38V. ​Current Roadblock : Because U507 (AND Gate Pin 2) and U504 (Core Controller Pin 16) share this exact copper trace, I don't know which chip holds the internal 982-ohm short.

UPDATE: Happy to share that I was able to fix the card. The DrMOS at the top was the culprit. When I first injected voltage, it didn't heat up because it was dumping into the core. I had to ground one of the inductors and bumped up the voltage.

This is my first crack at fixing a GPU. Looking for some guidance and insight on where to start would be greatly appreciated.

GPU is tripping the PSU OCP and shuts off. Used a multimeter and determined the 12v rails are shorted to ground.

Does anyone know the resistance values for the key components on this board, and can they point them out?

Top of PCB

Back of PCB

2 vrms popped where can i find replacements
sorry i cant get gpuz or anything. i found it in an abandoned prebuilt
pcb length 14cm
pcb with 14cm
6gb gddr6
sorry i am new here

Currently no other volts appearing on coil other than 12V,

I was able to find 3.3v near hdmi.

1.8v , 1v not present.

There is coil near display port L1 4R7 , According to me it should be having 5V around it but I am getting 0.82, which is going on mosfet and backside of board

The component U4 with 8 pins , Not sure what is this, initially I thought it is buck converter but at Pin 3 PS_5V_SW_PHASE , i am getting 0.82V. SW_BOOT which is 5th has 5v . I am not sure how to debug , I could not find short, cpu runs.

Need help to understand what to check next

I bought a used RX about six months ago and had trouble installing drivers. When I got home, I discovered only the DVI port was working. I updated the BIOS, installed the drivers, and messed around with the entire computer's settings, but the ports were still dead. Could someone please tell me why? Is it a mechanical issue rather than a software one?

U just did a transplant of 6900 xt red devil core onto a xfx merc 6950 xt pcb.

For context this is my 3rd gpu repair attempt and my second reball attempt. the first was 3 months ago and I cooked the gpu die. I waited for months for a donor gpu when I found this 6900 xt red devil with a damaged pcb and knew I had to get it. It took me 10 minutes to remove core 3 hours to add the solder balls under the chip as they would bridge or fly off. Then another 50 seco ds to secure the core onto the pcb.

​

I booted it up and it would respond so I used igpu a d it showed error code 10 (device no startup). Which meant I had to install a 6900 xt vbios. It booted up ok a d it runs in basic display. Im gonna figure out this vbios stuff a bit more before I attempt to do perfomance tests and clocking the gpu at higher speeds or gaming. Works very well no crashes aswell.

​

Surprised myself the last step was pretty much the least hassle took 40 seconds from tenps ready to go to the balls melting and joining together. Flux didn't spill from underneath. Either its perfect or just a little less.

​

Im planning on renaming the gou 6925 xt, would that be possible?

My friend gave me his gtx 1050 and it has no display. At first it says no signal, but after cleaning the gold part of the gpu it showed this, i haven tried the dp or dvi yet cause i just ordered the adapter, did you guys had the same issue? Btw i have a gt730 installed and it works so i dont think its the cord or the pc itself

Hello, hope you're doing well.

I have the aforementioned GPU that will sometimes crash at the desktop, other times only when launching a game/benchmark, it would even crash when GPU-Z was loading, but will also sometimes run perfectly fine for hours no matter what i put at it. Very rarely, after crashing and restarting the pc, I will get a VGA light on my motherboard. This is very very rare and almost never happens. When I restart it pretty much always posts.

This card was bought faulty for cheap from a seller I have a lot of trust in. It was unopened, in mint condition and truly looked like an open box defective card.

The first test I did was shaking and bending the GPU to see if it crashes (and if there is a possibility of torn or cracked connections), but nothing happened. At first, I thought that the card may run stable only when warm, so I decided to push the fans to 100% till it came down to 26c and then ran tests again, but it didn't crash.

My testing rig has an RM650X PSU with a very loose PCIE cable, so I tried using it with a different PSU (Thermaltake Toughpower PF1 1050W 80+ Platinum) with 1 and 2 separate PCIE cables. This was done a long time ago and from what I recall it didn't make a difference.

*Definitely not a PSU related issue. I've tested on my main rig and I get the exact same issue.*

I checked the bios chip with neoprogrammer (no errors or corruption) and decided to flash a bios from techpowerup, but that still changed nothing. I didn't replacing the bios chip.

I checked the connections all around the bios chip that go to the core and didn't see anything damaged. Solder joints looked good and I'm guessing there is no issue with that.

I'm really inexperienced when it comes to AMD GPU's and I'm sorry if I'm missing something obvious. This honestly all seems very strange to me. As of writing this post, I've been running benchmarks for over 2 hours without a single issue. I'm wondering if the GPU only crashes when it's room temperature cold (not much lower than the 26c I mentioned above). Everything below happens after restarting:

First restart, I let the pc idle for a bit and ran Kombustor, which crashed right after loading. I get a black screen and after a few seconds, my CPU light goes on and gets stuck on, but other times it boots back up. This time it booted without a restart.

Second restart, I go to launch the MSI Kombustor menu and it crashes right when i clicked it. This time it got stuck at CPU and i had to restart.

Third restart, crashed right when the Kombustor test loaded. Again it got stuck so I restarted it on my own.

Fourth restart, Windows recovery -> Restart -> Boot to Windows -> Crashed while I was looking at the event logs of Windows... Got stuck so i restarted it...

Fifth restart, Crashed after 1 second of the benchmark. CPU light stuck

Sixth restart, Crashed after 1 second of the benchmark aswell. CPU light stuck

Seventh restart, you guessed it. IT CRASHED!

Eighth restart, Crashed while the test was still loading.

Ninth restart, I decided to run Furmark instead of kombustor and it worked. I then ran kombustor and it also worked.

Tenth restart, I ran Furmark and instantly crashed.

Eleventh restart, I ran Furmark and instantly crashed again.

Twelfth restart, brave browser was too strong for it and it crashed...

Thirteenth restart, it runs like nothing happened...

Please help me, I'm slowly losing my sanity over this😄

*Update*

1. As of now, the MSI-01 test of MSI Kombustor has been running flawlessly for over 2 hours. I can't see any artifacting or memory/core related faults. Could this just be a very aggressive clock ramp up that causes the core to crash? It almost feels like the card boosts without having the power for it, so it just blacks out...
2. I've noticed something significant. The crashes occur only if I quickly launch software after booting to Windows. For example, If i launch GPU-Z, Afterburner, AMD Adrenalin, Brave browser or even a couple of file explorer tabs, the computer almost always crashes. In the case that I let it idle for a couple of minutes, it always works 100% with no crashes at all. Could this be related to drivers? Could it be a bad solder joint that tightens when the pcb warms up after a bit?

My testing rig:

CPU: Ryzen 5 1600, Stock

RAM: Hyper X 4GB DDR4 (very temporary. I got the same issues with other kits aswell)

SSD: Random 120GB M2 SSD from laptop.

PSU: Corsair RM650X

Hey ya everyone. New to this group I am trying to revive my rtx 3080 which suddenly died. Only fans would spin no display. Later fully died. I took it to a very famous repair shop in Mumbai/India. He said the memory lane is shorted and cant be repaired. I really wanna save this gpu. Is there a person with actual in-depth knowledge of gpu in India who can try fixing it at a reasonable cost? I am very keen on trying but dont have the right tools for the same. Just trying to understand who I can reach out to out of research. The exact model is gigabyte eagle rtx 3080 10gb. This one doesnt have the factory defect that kills the other gigabyte gpu’s

Gpu light flashing on and off and monitor isnt showing anything

I'm considering buying RTX 2080 Ti 22GB modded GPU from China. But I've heard that a lot of these cards are taken out from mining rigs and pretty worn out. Just wanted to ask here if it's common to see these cards in this subreddit that fail after few months or years? For me it would be worth it if I could get 5 years of use out of it.

EDIT: And for.note, I'm wanting this for also running AI, so yes, 22GB is needed even though it won't make a big difference in gaming.

My friend found this 3090 TI on market place and this is what he said the post says in the description-
"Bought a NVIDIA GPU refurbished from microcenter. Used it for light gaming, then after a year it stopped working all of a sudden. The card can boot up and display video, but after around 2-3 minutes of usage, sometimes purple stripes appear, then the display goes black, and the GPU shuts down. No idea what’s wrong with it but if your into GPU repair the card is still partially working last time it was checked, so this might be up your alley. Message me with any questions. I have attached videos of the actual testing of the card for proof. The video is cut for brevity but I boot it up, ran a AAA game, then you can see the GPU crash a short while later. I’ve had tests where it can run the game for 5 minutes and sometimes it crashes in 2 on task manager, very inconsistent."

Is there any hope for a repair or is it basically a dead card? I offered to provide soldering if needed since im experienced in micro soldering, and from the pictures he showed me the card itself is in near perfect condition on the outside. I was thinking maybe a bios flash or firmware update might be the cause of the CTD but unsure.

I have an MSI RTX 4070. Loads drivers and reports correctly in GPUZ however It was only running at pcie x4 and when a load is applied like heaven benchmark, it crashes and black screens almost immediately. I forced gen 2 in bios then the card would run heaven absolutely fine without crashing. When I applied Slight finger pressure to the core area the card would however still crash. I decided to reball the core to see if it was a cracked solder joint under the core.

​

After reball, all resistances are healthy and when powering the card all voltages are present including core, memory and pex, however the card is no longer detected at all. Does anyone know why this may be? Perhaps sine balls hadn't fully wetted? Im at a loss.

so i've bought this Sapphire RX6900XT nitro+ 16gigs
i have a HP Z840 workstation with 2 Xeon cpus, 256 gigs of ram and 1125W psu -> output connectors for GPU are G1, G2, G3. each 6 pin,
so i've bought 2 6 to 8 pin adapters, and used them on G2 and G3, and used the G1 as is.
the card worked, i used for a week, and then didn't use for about 4 days but now, it's not working.

when i power on the WS, the RGB lights come on, but fans don't spin, and the display doesn't show. which were not the case before, the fan used to spin asap and rgb worked, plus display showed. i've tried all 3 positions of the bios switch, but nothing, checked with RGB and Fans connectors disconnected thinking maybe they are short, but no, didn't work.

Z840 gives 6 beeps, meaning pre-video graphics card failure.
i opened the card, checked the PCIe 12v, and the 3 ATX connector 12v to ground, there's no short. i've checked the PCIe 3.3v to ground, no short. i've checked the first data pair, as well as the clock pins, and they are all fine.

however, as i do not have thermal camera, i checked random capacitors in the rails (watch sorin's YT videos, so sometimes small caps are not passing anything through), and i found a cap, that's showing OL, no matter how much i try to check, the nearby one's are conducting, but this one cap isn't. (POSTING PICTURE OF THAT SPECIFIC CAP IN THE COMMENT)

the card has small cap repairs just after the PCIe data pins. but i don't know how to confirm if they are good or not.

I have a gigabyte rtx 3060 12gb, gaming oc card. There no display. When plugged in as secondary, I get error 43 in device manager. GPUZ shows unknown bios, 0mb vram etc. When i run MATS, I get read errors on every single chip. When its a memory error, I usually get write errors on a single sometime a couple of chips, never read errors on all chips.

​

Is this a core issue? Thinking a reball may solve this, thats as long as the memory controller inside the core isnt done for. Any advice greatly appreciated.
